Packing box for a weight lifting bar

ABSTRACT

A packing box for a weight lifting bar includes an elongate board having four parallel first folding lines to define the elongate board into a first portion, a second portion, a third portion, a fourth portion and a fifth portion. A second folding line is formed in each of two ends of the elongate board. Each of the two ends of the elongate board is defined into five end covers by the second folding line and the four first folding lines. The first portion is cut to have two side covers. The fifth portion is cut to have two openings. The elongate board is folded along the four first folding lines to form a quadratic body, and the end covers are folded inward to close the two open ends of the quadratic body. The bar in the packing box can be seen via the openings by opening the side covers.

BACKGROUND OF THE INVENTION

1. Fields of the invention

The present invention relates to a packing box, and more particularly,to a packing box for receiving a weight lifting bar therein, and the barcan be seen via openings of the packing box.

2. Descriptions of Related Art

The conventional weight lifting equipment such as barbells and dumbbellsgenerally comprise a bar and two weights which are connected to tow endsof the bar. The user holds the bar and lifts the barbell or the dumbbellto train the arm muscles. The bar and the weights are packed separatelyin stores. The conventional packing box for the bar of a barbell or adumbbell is disclosed in FIGS. 6 and 7, wherein the packing box 8 is acylindrical and hollow paper tube 81 with certain thickness. The bar 9is received in the packing box 8 and two plastic covers 82 are used toseal the two open ends of the packing box 8. The two covers 82 aresecured by tapes 83 so that the customer can hold the packing box 8while the bar 9 in the packing box 8 does not drop from either of thetwo open ends.

It is noted that the manufacturing cost for the packing box 8 is high,and the two covers 82 are required to seal the two open ends of thepacking box 8 by tapes. However, the bar 9 is movable in the packing box8 and the cylindrical packing box 8 may slip from the customer's hand.Besides, the cylindrical packing boxes 8 are difficult to be piled upand occupy a lot of space. Furthermore, the customers cannot see the bar9 in the packing box 8 if the tape 83 and the covers 82 are not removedfrom the packing box 8.

The present invention intends to provide a packing box for receiving abar therein, the packing box has openings for observation of the bar andeliminates the shortcomings mentioned above.

SUMMARY OF THE INVENTION

The present invention relates to a packing box for a weight lifting barand comprises includes an elongate board and four first folding linesare formed in parallel to the elongate board so as to define theelongate board into a first portion, a second portion, a third portion,a fourth portion and a fifth portion. A second folding line is formed ineach of two ends of the elongate board and perpendicular to the fourfirst folding lines. Each of the two ends of the elongate board isdefined into five end covers by the second folding line and the fourfirst folding lines. The first portion is cut to have two side covers,and the fifth portion is cut to have two openings located correspondingto the two side covers. The elongate board is folded along the fourfirst folding lines to form a quadratic body, and the end covers arefolded inward to close the two open ends of the quadratic body. The baris received in the packing box and can be seen via the openings of thefifth portion by pivoting the side covers of the first portion.

Preferably, each of the side covers has a notch defined in the distaledge thereof.

Preferably, the distance between the two side covers is substantiallyequal to a user's shoulder width.

Preferably, the elongate board is a paper board.

The primary object of the present invention is to provide a packing boxof a bar wherein the packing box has two openings through which the usercan hold the bar.

Another object of the present invention is to provide a packing box of abar wherein the packing box has two openings through which the bar canbe seen.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, the packing box 10 of the present inventioncomprises an elongate board which is made by paper, and four firstfolding lines 101 are formed in parallel to the elongate board. The fourfirst folding lines 101 define the elongate board into a first portion11, a second portion 12, a third portion 13, a fourth portion 14 and afifth portion 15. A second folding line 102 is formed in each of twoends of the elongate board and perpendicular to the four first foldinglines 101. Each of the two ends of the elongate board is defined intofive end covers 16 between the second folding line 102 and the fourfirst folding lines 101 by cutting along the four first folding lines101 and being ended at the second folding line 102. The first portion 11is cut transversely four positions to form two side covers 111 which areable to be pivoted away from the first portion 11. The fifth portion 15is cut to have two openings 151 which are located corresponding to thetwo side covers 111.

Referring to FIGS. 2 and 3, the elongate board is folded along the fourfirst folding lines 101 in sequence so as to form a quadratic body,wherein the first portion 11 is overlapped on the fifth portion 15 asshown in FIG. 5. The first portion 11 is secured to the fifth portion 15by any known method such as gluing or stapling. The end covers 16 of oneend of the quadratic body are then folded inward, and tapes are used toconnect the end covers 16 and to seal the open end of the end of thequadratic body. The bar 9 is then received in the quadratic body fromthe other open end of the quadratic body, and the same steps are takento seal the other open end of the quadratic body. The elongate board iscorrugate paper board which provides suitable cushion feature.

As shown in FIGS. 4 and 5, there are two openings 151 defined in thefifth portion 15 and the two side covers 111 are located to cover up thetwo openings 151. Each of the side covers 111 has a notch 112 defined inthe distal edge thereof, so that the customer can easily pivot and openthe side covers 111 by insertion a finger into the notches 112. Byopening the side covers 111, the bar 9 in the packing box 10 of thepresent invention can be partially seen. By this way, the customer cancheck the bar 9 in the packing box 10. Besides, the distance between thetwo side covers 111 is substantially equal to a user's shoulder width,so that the user can easily hold the bar 9 via the openings 151.

The packing box 10 is easily piled up and the open ends of the quadraticbody are sealed by the end covers 16 and tapes 18. No plastic covers areneeded. The customers can check the bar 9 in the packing box 10 via theopenings 151, and the customers can hold the bar 9 through the openings151 without worry of slippery surface of the packing box 10.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
